Question 1

What is the primary benefit of runtime polymorphism?

  • Code Redundancy
  • Code Reusability
  • Increased Complexity

💡 Hint: Consider how polymorphism helps you avoid repeating yourself.

Question 2

True or False: Method overriding allows a subclass to have a method with a different signature than its superclass.

  • True
  • False

💡 Hint: Think about how method signatures interact between classes.

Challenge Problems

Push your limits with challenges.

Question 1

Design a simple Java application that simulates a zoo. Implement a base class Animal with overridden methods for different animal types, like Lion and Elephant. Explain how runtime polymorphism helps in managing the behaviors.

💡 Hint: Think about how you can use a common reference type for different derived types.

Question 2

How does the use of method overriding simplify code structure in an application with multiple payment methods (CreditCard, PayPal)? Outline the advantages.

💡 Hint: Emphasize how polymorphism can reduce duplication and enhance flexibility.
